In this engaging conversation, Dr. Mark Laslett, a musculoskeletal physiotherapy specialist from New Zealand, and Greg Lehman, a physiotherapist and chiropractor with a biopsychosocial approach, tackle the contentious issue of non-specific low back pain. They debate whether it qualifies as a real diagnosis and discuss its implications for patient treatment. Their dialogue brings to light the current research gaps, challenges in diagnostic accuracy, and the need for individualized care strategies, making a compelling case for a reexamination of traditional approaches.
